REVUE BRYOLOGIQUE 97 
À Contribution to the Bryology of Tornean Lapland ; 
with a discussion on the relationship of Mnium 
hymenophyllum and M. hymenophylloides. 
By H. N. Dixon 
The Bryology of certain parts of Tornean Lapland has received 
some attention of recent years, the Swedish Railway through the 
mining districts of Gellivara and Kiruna having opened up the 
country, and rendered the rich botanical district about Kvickjokk 
somewhat more accessible than heretofore. As far as Iam aware, 
however, there has been nothing hitherto recorded from the still 
more northerly district immediately bordering on the Tornea 
Träskt, so that some notes on the bryology of that district may 
perhaps be of interest, especially as it is probably the most nor- 
therly inland region of the European continent that has been 
investigated with any care from a bryological point of view, with 
the possible exception of the Kola Peninsula. 
The country about Abisko has been brought within reach of 
tourists through the enterprise of the Svenska Turistfüreningen, 
by which Club a small Turiststuga or Hut was opened at Abisko 
a few years back. This has proved so attractive that it has been 
gradually enlarged to a moderate sized hotel, which if not replete. 
with every modern luxury is quite sufficiently comfortable for a 
field botanist. À subscription to the Sv. Turistfüreningen gave my 
friend Mr. W. E. Nicholson and myself the entrée to the Stuga or 
-Hut, as in spite of ils growing dimensions it is still called, and 
we spent ten pleasant days there in the latter half of August, 1907. 
Abisko is a station on the mineral railway at about the middle 
of the southern shore of the great Tornean Lake, which extends 
for about 60 miles in an east and west direction just north of the 
68th. parallel of latitude. The station was made merely forthe 
purposes of the mineral traffic, there being no population in that 
district beyond a few small tribes of nomadie mountain Lapps. 
The Turiststuga is situated two miles west of the station, on the 
margin of the Abiskojokk, a stream of some size which atthis 
point has worn itself a canon some half a mile in length, with 
perpendicular eliffs of limestone 50 feet or so in height, before + 
emptying itself into the Tornea Träsk. From the western side of 
this stream the ground rises almost at once to the mountainrange 
the central part of which forms the boundary between Norway end 
Sweden, with summits of from 1200 m. to 1800 m. At this latitude 
snow lies all the summer in large patches down to 1000 m., and 
_ the glaciers descend to 1200 m. East of the Abiskojokk the ground
